Letter: Electron-Impact Mass Spectrometry in Analysis of Isomeric Alkoxycarbonylalkylthiouracils—A Correlation of M+• Intensities and Selected Fragment Ions

Abstract

The correlation between the intensities of M+• and the selected fragment ions on basis the mass spectral fragmentation of thirty-two 2- and 4-alkoxycarbonylalkylthiouracils were discussed. The data obtained create the basis for distinguishing isomers.
